The Wireless Channel-oriented Ad-hoc Multi-hop Broadband (W-CHAMB) is a new link layer protocol with the aim of being able to support Quality of Service (QoS) in multi-hop operati...
We study a wireless network under the 802.11 random access protocol, supporting multiple physical layer rates. Based on models for the effective packet rates achieved at the MAC ...
Third generation wireless systems can simultaneously accommodate flow transmissions of users with widely heterogeneous applications. As resources are limited (particularly in the...
Abstract--We consider the problem of coding images for transmission over error-prone channels. The impairments we target are transient channel shutdowns, as would occur in a packet...
